DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0009]As required, detailed embodiments of the present invention are
disclosed herein; however, it is to be understood that the disclosed
embodiments are merely exemplary of the invention that may be embodied in
various and alternative forms. The figures are not necessarily to scale;
some features may be exaggerated or minimized to show details of
particular components. Therefore, specific structural and functional
details disclosed herein are not to be interpreted as limiting, but
merely as a representative basis for teaching one skilled in the art to
variously employ the present invention.

[0010]Referring now to FIGS. 1-3, a chair is illustrated in accordance
with an embodiment of the present invention and is referenced generally
by numeral 20. In at least one embodiment, the chair 20 is an office
chair having a base 22 with casters 24 for supporting the chair 20 upon
an underlying support surface, and for transporting the chair 20 upon the
underlying support surface. The chair 20 has a seat bottom 26 that is
mounted to the base 22 for seating and supporting a user. The seat bottom
26 may include a frame that is covered with cushioning, such as foam
padding, and a cover.

[0011]A seat back 28 is mounted to the seat bottom 26 for receiving a back
of the user and for supporting the back of the user. Similar to the seat
bottom, the seat back 28 includes a frame that is covered by cushioning,
which may be foam padding, and a cover.

[0012]The chair 20 also includes a pair of armrests 30, 32 that are each
mounted to an underside of the seat bottom 26 and extend upward from
lateral sides of the seat bottom 26 for receiving and supporting the arms
of the user.

[0013]As is known in the art, each of the structural features of the chair
20 are adjustable. For example, the height of the seat bottom 26 is
adjustable relative to the base 22; a resistance spring force upon the
tilt connection between the seat bottom 26 and the base 22 is adjustable;
a tilt angle of the seat back 28 relative to the seat bottom 26 is
adjustable; and the height of the armrests 30, 32 relative to the seat
bottom 26 are adjustable.

[0014]The seat back 28 includes a peripheral frame that is padded with
cushioning and a cover 34. The cover 34 and underlying cushioning extend
around the periphery of the seat back frame, which includes a lower
pelvic region, side bolsters, and an upper shoulder and headrest region.
The back rest 28 also includes a central fabric cover 36 mounted within
the peripheral cover 34 and supported by the frame of the seat back 28.
In one embodiment of the invention, the cover 36 is a mesh fabric that is
mounted in tension to support the back of the user.

[0015]The seat back 28 includes a massage unit 38 that is mounted to a
rear side of the seat back 28 and is connected to the frame. The massage
unit 38 imparts a massage effect to the central cover 36 for massaging
the back and shoulders of the user. The massage unit 38 is selectively
detachable so that the user can utilize the chair 20 as a conventional
office chair with or without the massage unit 38, or so that the user can
utilize the chair 20 in combination with the massage unit 38 for seating
the user and imparting the massage effect upon the back of the user. By
providing the seat back 28 with a peripheral frame, and the central cover
36, the massage unit 38 can be selectively attached to the seat back 28
for providing the massage effect, or detached for providing a
conventional seating configuration with the central cover 36 in tension
for providing rear support. Alternatively, the massage unit 38 may be
replaced with a structural blank, such as foam or padding to support the
cover 36 from the rear.

[0016]Alternatively, multiple massage units 38 may be employed, each
having a varying massage effect such that the user can remove one massage
unit 38 and replace it with another massage unit 38. In addition, the
detachability of the massage unit 38 provides ease and servicing and
maintenance of the massage unit 38.

[0017]One such suitable massage unit is disclosed in Ferber et al. U.S.
Patent Application Publ. 2007/0060851 A1, which published on Mar. 15,
2007 and is incorporated in its entirety by reference herein. The massage
mechanism may be imparted directly to the underside of the central cover
36 so that the rollers provide rolling and kneading massage effects upon
the back of the user.

[0018]Other known suitable massage units 38 can be utilized in combination
with the chair 20 in accordance with the present invention such as rotary
kneading massage units, hemispherical roller massage units, percussion
(tapping) massage units, and any other suitable massage unit that can be
contained within the massage unit such as massage unit 38 and installed
into the seat back 28.

[0019]Referring now to FIG. 4, one of the armrests 30, has a docking
cavity 40 formed therein for receiving a remote controller 42. As
illustrated in FIGS. 1-3, the remote controller 42 is received within the
cavity 40 of the armrest 30 to provide a generally flush and uniform
appearance of the armrest 30. Referring again to FIG. 4, the user can
deploy the controller 42 from the armrest 30 for operating the control
features of the massage unit 38.

[0020]Referring now to FIGS. 5 and 6, the remote controller 42 is
illustrated with functions that are associated with a suitable massage
unit 38, such as the massage unit of the Ferber et al. U.S. 2007/0060851
A1 patent application publication. The remote controller 42 communicates
with the massage unit 38 via wireless communication. Thus, the remote
controller 42 transmits a wireless signal, such as a radio frequency
signal from a radio frequency transmitter to a radio frequency receiver
within the massage unit 38. Alternatively, the remote controller 42 can
communicate with the massage unit 38 by infrared or any other suitable
wireless communication. Although wireless communication is described, the
invention contemplates that the remote controller could be hardwired and
tethered to the chair 20 or directly to the massage unit 38. Wireless
communication permits ease of use and interchangeability of the
controller 42 and the massage unit 38.

[0021]The remote controller 42 includes a power button 44 for turning the
massage unit 38 on and off. The remote controller 42 also includes
controls for the kneading massage effect and the rolling massage effect
provided from the massage unit 38. Each button on the remote controller
42 may include a light emitting diode (LED) for indicating that the
associated function is in operation.

[0022]A full back shiatsu massage effect button 46 is provided for
selecting a kneading and rolling massage effect to the full longitudinal
range of the massage unit 38. An upper back shiatsu massage effect button
48 and a lower back shiatsu massage effect button 50 are also provided
for controlling a kneading and rolling massage effect to a targeted range
as defined by limits within the massage unit 38. The remote control 42
further includes an upward targeted kneading massage effect button 52 and
a downward targeted kneading massage effect button 54 for providing the
kneading massage effect to a targeted region upon the user's body.

[0023]A full back rolling massage effect button 56 is provided on the
remote controller 42 for providing a full rolling massage effect from the
massage unit 38. An upper back rolling massage effect button 58 and a
lower back rolling massage effect button 60 are also provided for
generating the rolling massage effect within a targeted range as set
forth by limits within the massage unit 38. A width adjustment button 62
is also provided on the remote controller 42 so that while a user is
experiencing a rolling massage effect, as selected by one of the rolling
massage effect buttons 56, 58, 60, the user may adjust the width of the
massage rollers.

[0024]In one embodiment of the invention, the remote controller 42
includes a heat button 64 for controlling a heating function of the
massage unit 38. Of course, the invention contemplates utilization of
massage units without heat. The remote controller 42 further includes a
demo button 66 for providing a demonstration operation of various
combination of the massage effects provided by the kneading and rolling
buttons 46-62 so that the user experiences a variety of massage effects.

[0025]Referring now to FIG. 7, the remote controller 42 includes a finger
well 68 formed in its underside to assist in removal from the armrest 30.
Thus, the user can extend his or her fingers about the armrest 30 to the
finger well 68 for pulling the remote controller 42 from the armrest
cavity 40. In at least one embodiment, the remote controller 42 may
cooperate with the armrest 30 through a latch mechanism such that the
remote controller 42 must be unlatched before removal.

[0026]While embodiments of the invention have been illustrated and
described, it is not intended that these embodiments illustrate and
describe all possible forms of the invention. Rather, the words used in
the specification are words of description rather than limitation, and it
is understood that various changes may be made without departing from the
spirit and scope of the invention.
